Merge policy per chart

[Giorgetto]

Hello,

I would like to configure two different chart (with the same instrument) with different merge policy, is it possible?
I know I can change the merge policy globally in the options and per each instrument, but I need the same instrument with different policy.
I've already tried to duplicate the instrument but I receive the "Unknown instrument" error, I've copied all symbol map, is it correct this error?

UPDATE:
After restarting the NT8, I don't receive the "Unknown instrument" error, but I don't receive the data, chart still black and empty.

Thanks for your help.
Best regards.

Hello Giorgetto,

Unfortunately, the Merge Policy is set either globally for all instruments or for a specific instrument. It would not be possible to set this for a specific chart.

If making a copy of an instrument be sure the symbol is unique. You can leave the symbol mapping blank except for Simulated Data Feed with the new fake symbol as it is not a real instrument and will not be able to pull real-data, and the symbol mapping cannot be shared between two instruments.

Then export the historical data from the real instrument, change the exported text file name to the new fake symbol, and re-import.

The chart will be empty until you import historical data for the fake symbol.
